Figure5

Figure 5. This figure shows the observed September sea ice extent for 1952-2011 (bold black line) and extents for 1900-2100 from the CMIP3 models using the “business as usual” SRESA1B greenhouse gas emissions scenario (the pink line averaging results from all of the model runs with the pink shading showing the +/- 1 standard deviation of the different model runs) and from the CMIP5 archive, using the RCP 4.5 scenario (blue line and blue shading). The darker pink shading shows where the simulations from CMIP3 and CMIP5 overlap each other. ||Credit: National Snow and Ice Data Center courtesy Stroeve et al. 2012 |{a href=http://nsidc.org/arcticseaicenews/2010/08/a-most-interesting-arctic-summer/figure5-8/}High-resolution image{/a}|
